Vehicle start-stop control method and device, ACC system and readable storage medium

Abstract

The invention discloses a vehicle start-stop control method and device, an ACC system and a readable storage medium, the vehicle start-stop control method is applied to the ACC system, the ACC system is electrically connected with an engine management system, and the method comprises the steps that when the ACC system enters a follow-up mode, obtaining traffic condition information of a current driving road of a vehicle, determining waiting time required for current parking of the vehicle according to the traffic condition information; judging whether the waiting time is higher than a threshold; if yes, starting a start-stop permission mode, and performing automatic start-stop control on the engine management system in the start-stop permission mode; and if not, starting a start-stop forbidding mode, and controlling an engine of the engine management system to enter an automatic start-stop forbidding state in the start-stop forbidding mode. The follow-up starting function of the ACC system is combined with the engine starting and stopping function configured for the whole vehicle, automatic starting and stopping of the engine are achieved in the ACC follow-up mode, fuel oil is saved, and the NVH of the whole vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a vehicle start-stop control method, device, ACC system and readable storage medium. Background technique [0002] With the impact of emission and fuel credit policies, the current engine automatic start-stop mode has almost become the standard configuration of vehicles. In the congested or traffic light intersection waiting for a long time, turning on the automatic start and stop can save fuel and improve the NVH of the vehicle. [0003] The existing engine start-stop mode is realized by the engine management system. The engine management system detects the state of the vehicle itself, and turns on the engine start-stop mode when the body state reaches the trigger condition. The trigger conditions include water temperature, battery SOC, vehicle speed, brake pedal, etc. [0004] This current approach often results in unintended stop-start activation by the driver. ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above situation, it is necessary to provide a vehicle start and stop control method, device, ACC system and readable storage medium for the problems of poor energy saving effect and poor user experience of the automatic start and stop function of automobiles in the prior art
